To all whom it may concern:

Be it known that I, IRA F. h lA'NNY, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Means for Se lective Signaling, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention has for its object to pro vide means for selective signaling which will enable a signal being given at. one or more of a number of substations in a telephone or other system without signaling the other stations on the same circuit therewith, which means will be simple in'its construction and operation, etlicient and inexpensive to manufacture and maintain.

The invention relates to means for selective signaling of the type wherein a magnetically operated anchor pawl is caused to permit an eseapemcnt of a toothed disk to a greater or less degree, according to the numher of selective impulses sent over the line, whereby one of the instruments is brought to a position in which it makes a connection for producing a signal, either by means of a signaling impulse over the line, or otherwise, said anchor pawl being then automatically released from the toothed disk permitting; it to turn, it being one object of this invention to simplify and ii'nprove upon the mechanism for causing the anchor pawl to release the toothed disk.

Another object o'l the invention is to pen mit oi. the signal heing given at any number oi sub-stations on the circuit which may he desired to he signaled at one time.

Another ohject of the invention is to provide each suh-station with means for signal ing and talking with central evccpt when the line is already in use, the talking circuit of the slili-Slullti'll at such lllllt' being locked out of the line circuit.

Another object of the invention is to pro vide means. of novel construction for automatically rcwinding the motor which turns the cscapemcnt disk.

jAnother object of the invention is to pen feet details of construction of mechanism of this character.

With the above and other objects in vicw, the invention consists in means .tor selective shown in Fig.

I3 is a rear view of the locll cd disk, showing the insulated mounting of the signaling tooth tlicrco't: Fig. 14 i a drt-ul view of the automatic drop mcvhanis -rm. Fig. 1a is a diagram of circuit connections of Ulli oi the instruments with the control station; and Fig. 'l6 is a diagram 1 i circuit connections of the motor rewind in g; mechanism.

In these drawings the instrument is shown built. upon a frame comprising; a front plate .30 and a back plate 21 connected by spacing posts 22, as common with ordinary chick-work mechanism. A. motor shaft 23 is iouroalcd through the front and hack plates ol" the fralneaud extends beyond the lront plate to a considerable extent, a LFE. This motor shaft ispgiven a tendency to turn by means of a coil spring 24: which is contained within a balance wheel The balance wheel is loosely mounted on the shaft, but carries a ratchet wheel 26 engaged by spring pressed dogs 27 on a gear wheel 28 which is fixed on the motor shaft. The pressure of the spring 24, which has its outer end anchored on the frame and its inner end connected with the balance wheel, is imparted to the motor shaft through such ratchet connection, which. is best seen in Fig. 11. As also seen in Fig. ll, the motion of the motor shaft, besides ei1g controlled by mechanism to he later dcscrihed, is re tarded by a star wheel. escapement which comprises a pinion 29 meshing with the gear wheel 28 and carrying gear wheel 30 which meshes with a pinion 31 carrying a star wheel 32 engaged by an escapement pawl 83 in the well known manner.

On the projecting front end of the motor shaft, as best seen in Fig. 12, there is first a shoulder 3% fixed in place thereon and havby means of a sleeve 36 surrounding the shaft and engaged by a nut 37 threaded on the end of the shaft. A. starting arm 38 and a locking arm 39, at an angle to each ther and preferably formed of a single piece of metal, as shown, are mounted on the front end of the motor shaft and are keyed thereto with a certain amount of play, having a pin 4:0 through the front end of the shaft enter larger recesses of said arms, the nut 37 having been removed in Fig. 4 to show this relation of the parts. These arms 38 and 39 are adapted to be engaged by a spring retracted anchor pawl 41, which is pivotally mounted on the front plate of the frame in a manner to be later described in detail, and which constitutes the armature for an electric magnet 42, whereby it may be swung out of engagement with the arms to release them and permit the motor to run.

A toothed disk 4-3, having its periphery toothed at different distances from the center and engaged by the respective ends of the anchor'pawl I the sleeve 3G-,'(sec Fig. 12) though it has a yielding spring connection therewith. This connection comprises a light coil spring 4% with its inner end secured to the sleeve 36 and its outer end secured to a spring to which is mounted on the back of the disk 4-3 and incloscs said spring 41. Thus, when the motor shaft isrclcased its turning movements tend to turn the toothed disk, but the toothed disk may be detained by its engagement with the anchor pawl, the turning of the motor shaft meanwhile serving to tighten the spring at, so that when the toothed disk is released it will follow the nun'cuionts of themotor-shaft until a stop tug iii thereon the starting mg a cam disk held tightly against it.

41, is loosely mounted on The spring cage is desirably formed of a disk of sheet metal with projecting arms 4t? bent forwardly and passing through openings in the disk where-they are then bent over, while other arms 48 bend rear- -.wardly and into notches in the edges of a contact disk 49 which is back of the spring cage and is insulated therefrom by having a sheet of insulating material 50 between them. The sheet of insulating material in practice isv a thin fiber sheet which is stamped in disk form with projections or tabs at its edges to fit beneath the arins l8 of the spring cage as they bend. around the edge of the contact disk. The insulating disk is placed between the disk of the spring cage and the contact disk and its projecting tabs are bent around the edges of the contact disk within the notches thereof by the operation of the forming dies wh'ich'bend the arms 48, thus locking these parts firmly together while at the same time keeping them insulated from each other.

'lhe contact disk is engaged by a spring brush 51 mounted onand insuiated from the front plate 20 and a contact arm 52 projecting from the contact disk is bent to lie within a recess in the toothed portion of the disk '13, forming axcontact tooth 53 to take the place of one of of teeth which corresponds to the number of the instrument. The instrument shown in the drawings is No, 5 and the contact tooth 53 is the fifth cscapemeni toothin the series, the first tooth being not considered as it is normally engaged by the anchor pawl in all instruments. 1

The anchor. pawl 41 is pivotally mounted on a screw stud 54: which is carried by a block 55 (Figs. 2 and 9) in turn pivotally mounted on trunnions in upturned cars 56 of a base 57 secured to the front plate 20. Thus besides the locking.movements of the anchor pawl to permit ()filllfi cscapci ocnt of the toothed disk and the release of the start ing and locking arms, it is capable of a swinging movement on an. axis at approximately right angles to the axis of its rocking movement whicn carries it nearer to or farther iromthc front plate so as to clear the plane of the toothed disk and the starting and locking arms.

In addition to the anchor pawl, the pivoted block carries a downwardly extending arm 58 and an upwardly extending arm 59, the former having a hall-shaped roller (=0 on its bent lower end which bears against the rear face 01" oem disk 35 and is holdfirmly in contact therewith by means of a coil spring (51 connecting the arm 59 with the base 57. The cam disk is provided with areccss or cam portion 62 into which the arm 58 springs when the motor shaft has turned to the position of the parts shown in Fig. ti, so as to swing the anchor pawl 11 the teeth of the first series 9 rig woman torqionul sq. .u g; h nurrounds tin: 7h one end (Hg i. hymn 5-1|liji15lr S llon said nrin noel ihrotho'r uni r lilo hiiitllfil{mWi H lo rolizru m ll zinrhor howl in its normal r nging-no :u uirh the toothed iiish us soon as its w no.1 nuigguot in rlelinorgirigd,

The wiring, of tho instrument, which is shown in Fig. 15 in iliugrznu, is, as follows: The line wires 95 and $36 connect the central station with i-hi SIIlJSCIliJGI' S station and at each subscribors staiion u wire 97 connects the line wirev 95 with the magnet 42 and a wire 98 conneots the other onal oi the magnet .130

fi l

, pawl 41 and consequently at that instrucontinuation oi switch tongue 68 while a. wire 99 connects the switch contact 69 with the ground, Hence, an impulse sent from the central station over the line wire 95, as by closing a switch 100 to connect a grounded generator 101 to said line wire, will pass through the magnet- 4:2, by way of the wires 97 and 98, the closed switch contacts 67 and 68 and the wires 99 to the ground. 'lhis int pulse energizes magnet- 42 and causes it to swing the anchor pawl 41. A number ct these impulses is sent from the central station, corresponding to the number of the substation desired to be signaled, and "for each impulse the instruments at all substations on that circuit have their toothecl disks advanced one tooth, the motor shafts having been released and set in operation upon the first impulse, when the starting arms 38 were released by the anchor pawl.

After the motor shaft has been in opera 'tion a sullicient length of time to enable t 1e operator at central to give the maximum number of impulses for which the instrument is adapted, the cam disk 35 brings its recessed portion (3:2 into position to receive the end of arm 58, whereupon the spring 61 causes the anchor pawl 41 to swing out of the plane of the toothed (lisk, releasing the same and permitting it to turn under the action of spring i l until the stop lug it engages the starting arm 38. Soon after completing the sending of the (lesirecl number oi selecting impulses, the operator at central station. sends a. ringing current over the line wires as by turning a magneto 102, connecting the line wires. At the substation cor responding in number to the number of se lective impulses sent, the contact tooth 53 will then be in engagement with the anchor winding to the ment this ringing circuit is cilective by passing over line wire tluthrough a wire 103 connecting it with the anchor pawl ll, through said contact tooth 53 of the disk 49 and the brush 51 bearing thereon, then through a wire lOl leading from sairl brush to one end of the winding of the chop mag net and through the armature hook of said rlrop magnet "which is connected by a wire 105 tothe other curl of the winding thereof, to the armature plate 89 and then by a way of a wire 106 which connects therewith to the other line wire 95. The magnet 90 being energized by this ringing impulse releases the armature plate 89 and permits it to fall into contact with the spring contacts 92-) and Jet respectively. The. armature plate 89 upon being disengaged from the armature hook 92 opens the circuit through the magnet 90, but its engagement with t} spring contacts 93 and ill. serves to connect a boil it)? and the telephoneinstrui ment lOll across the line wires so that the such. ringing; impulse or sue ceetiing impulse will cause the hell it)? the instrument to ring The circuit through the hell may be traced from line wire 95 to wire 106 to the armature plate 89 in engagement with the contact 93 and then ehrough the bell 10? which is connected between the contact 915 and the line wire 96 by means of a wire 109, The telephone instrument 108 is likewise lllcllldtll in the circuit thus established by the fall ot' the automatic drop since it is connected. between the wire 109 and contact 9 by means of a lit). wire 110 also connects with the spring; contact 6? normally engaged by the spring tongue 66 which is connected by a wire 11.1 with the line wire 95 in OItlEI that te ephone. instrument lllal may be normally con nected across the line to permit of the sub station calling anti communicating with central when the line is not in use, How ever, wnen the (lrop is operated, the cam tooth 65 which normally holds the switch contacts 66 anti in engagement is out of position to produce this eilect and at the time that all of the instruments are brought to a stop by the engagement of their locking arms 39 with thesnchor pawl, which has now been returned to its normal position, of the instruments except that one which signaled have their telephone instrumerits cut out of circuit by the opening of their switch contacts 6t? and 6! antl the sig nalerl instrument has its telephone set in cl'iuletl in the talking circuit the ment of the armature plate 89 with the contact 94 as tiesoribecl.

When the conversation is enietl, as indirated at the central station in any usual me iner, the operator at central station sends another impulse over the line by closing switch 100 and thus energizes the magnets 4% of all instruments, causing the anchor pawl ll to release the locking arms 39 and permit the motors to turn untilthe starting arms 38 are engaged. This clearing impulse to restore all instruments on the line to their normal positions, however, is made with the instruments in their talking position, as shown in Fig, 8,:inrl at such time the spring tongue 68 insteatl of being in engagement with the spring contact 69 is helcl by the care tooth in engagement with the spring contact '30 which is connected by a wire 11% with one curl. of the winqing of. resetting magnet 86, the other end t iercof being connect i by a wire 113 with the ground. llhus, the automatic drop of the sub-statioi'i signaled-1s reset by the l lac-h sub-station is provided. with a magneto li l or other signaling means connected across the line "sires preferably between wills 106 and 109 anrl'by means thereof the esters: station may be signaled.

i'hc ai'irin of the rewintling mechani sl'iown in rig. to, is such that the. nu

magnets. here shown, a battery 115 or -'other source of current supply is connected between the binding 73 and 81, so that .when the roller 71 contacts with the contact 74, the circuit may be traced from said battery tobinding post 73 and wire 72 to the roller 71- and the engaged contact 74, then through the winding'of magnet 7 5 and the wire 116 which connects the two magnet windings and through the winding of magnet 77 and by way'of wire 80 to binding post 81 to the battery. When the magnets 75 and 77 are energized, the movement produced thereby first causes them to be short circuited and then as the roller 71 leaves the contact 74, the circuit is broken, but the short circuiting of the magnets before breaking the circuits avoids the forming of an are at the contact roller.

It will be noted that if it is desired to connect more than one instrument on the line at one time, it isonly necessary for the operator at the central station to give the number of impulses corresponding with the lowest number desired and then send a signaling impulse to signal that station, and then follow immediately after with a number of additional selective impulses to make the total number of selective impulses a uni to the next higher number desired and t on send another signaling impulse and so on indefinitely, except that all signaling im pulses must be made before the instruments have advanced sufficiently to have their anchor pawls disengaged from the toothed disk.

By means of this invention the construction is simplified, reducing the cost of manufacture and insuring durability. The formation of the spring cage 1-5 in particular possesses advantages in its simplicity for the purposes intended, being; formed from a single piece of sheet metal with certain of its projecting tongues engaging and looking with the toothed disk to form an inclosure for the springei i and others of said tongues sccurely holding in its insulated position the contact disk 49 carrying the contact tooth 53, thus affording a means for rigidly mounting the insulated though electrically connected contact tooth onthe toothed disk, a feature of great importance in a device of this character.'

Another feature of construction possessing particular merit is the means employed in this invention for disengaging the anchor pawl from mounting of the anchor pawl whereby, it may swing latera ly for such disengagement as well as rock as usual for its cscapcment. The cam disk on the motor et -ft engaging the toothed disk, comprising the the arm of the spring acutated mounting for the anchor pawl constitutes a means of extreme simplicit and durability and cll'cctivencss for procuciug the disengagement of the anchor pawl from the toothed disk at a desired point in the cycle of operation of the device.

Another notable feature of construction of this invention lS'tllO motor spring rewinding mechanism which automatically rewinds the motor spring as soon as it has'run down to a certain extent, thus requiring of the motor spring a minimum amount of work to beperformed at each winding); and permitting the use of a light and inexpensive spring: that may be incased within the bal ance wheel for convenience and for economy of space.

. Another novel feature of construction comprises the switch mechanism operated by the cam disk in the different positions of the motor shaft and the automatic drop having circuit connections therewith and toether constituting a mcans for controlling the operation of the signal connections for the subscribers stations and for looking out the subscribers instruments when the line is in use.

It is to be understood that by means of this invention the subscribers station which has had its number called by the selective impulse may be signaled, not only by the signaling impulse which serves to throw the aui'mnatic drop thereof, but in event of the subscriber not promptly answering the call, it is only necessary for the operator at central station to send further signaling iln pulses over the line and these will be effective for ringing the subscribers bell, the parts remaining in their some positions from the time that the instrument is locked by the engagement of the locking arm 39 with the anchor pawl, and the succeeding fall of the automatic drop, throughout the talking connection and until the clearing impulse is sent. over the line from the central station to restore all instruments to their normal positions.

It will be seen that the position of the starting arm and locking arm will indicate the condition-of the line, that is to say, when the starting arm is engaged by the anchor pawl, the line is not in use, and when the locking arm is engaged by the anchor pawl, the line is in use, so that the subscriber may be informcdibeforc trying tocall central whether tho'l'ine is in use.

The objectof providing starting and lock' ing arms with a limited play or freedom of movement on the motor shaft is to avoid the possibility of the esctipemcnt of the toothed disk beinglretarded by the comparatively slow action the motor when the series of selective impulses is sent rapidly, as by mechanical means. As soon as the locking arm is released by the anchor pawl, it drops the distancepermitted by its play or loose movement on the motor shaft and thus takes a lead of the motor shaft which will enable the toothed disk to be immediately advanced the full distance of the arc of its escapement teeth without the stop to engaging the starting arm to retard the cscapement of the toothed disk,

The particular construction of the arma tare plate for the automatic drop and the core piece 87 of its resetting magnet is such that itis found to possess eliective attractive power throughout the arc of movement of the armature plate.

I desire it to be understood that this invention is not limited to any specific form or arrangement of parts except in so far as such limitations are specified in the claims.
